TUFT.

Specification ofiL'ettels Patent.

Patented June 1, 1909.

Application led September 12,- 1908. Serial No. 452,781.

To all eL-7mmlit may concern.'

' Be it known that I, EnNnsr KonLLa, a. citizen of the lfiiited States, residing atV Knoxville, in the county of Knox and State of 'l` -\nnessee,` have invented a iiew'and useful Improvement in Tufts, of which the lol-* lowing is specification, reference lbeing had to the accompanying dran-ing )ly iii'iprovenient relates particularl)Y to tufts used in the manufacture of mattresses," cushions, etc., a tuft being placed between the thread and the outer fabric ot the mat` thread froin drawing or cutting through such fabric.

The object of the invention is to produce a tuft which is to the highest degree soft and fluffy and is at t-he Sametime durable, all the yarn sections of which it is composedl being secured in such manner as-to avoid withdrawal thereof when the mattress is being handled or cleaned.' .Itis essential that such tufts be soft, in order that they may not be similar article. Various materials or artiventing the thread. from drawing through the fabric.. For example, an' ordinarywooden v01 rubber button would serve that purpose; but its presence would always be noticeable and objectionable in the use vof the mattress. Tufts have heretofore been made of yarn, the longitudinal strands or cords thereof beingheldtogether by Winding a cord around the bundle of said cords and harden the tuft and at the Sametime leaves all the cords, excepting those on the outside, more or less free to be pulled out, and after a few of saidcords have been pulled out, the entire tuft is soon destroyed and the thread which it Was intended to support is drawn through the mattress.

limprovement; Fig. 2 is a side elevation of I line 11H4: OFig. 1.

In the 'accompanying drawings, lFigure l is a side elevation of a tutt embodying my l the'iniddle portion of said tuft, the-yarn sections being represented 'as straight and not expanded; Fig. 3 is a similar elevation of I the' opposite side of the -iniddle portion of said tuft; Fig. 4 is an enlarged section o n the n' VReferring to said drawings, A, A, A are sections 'of light cotton cord or yarn. These are arranged parallel to eachother in sufhcient number to produce the-desired body or l thickness for the tuft. Approximately twenty-five or thirty of such sections have been .found satisfactory inl practice. Such yarn should be si soft 'as to permit the iniddle poi-tion (the portion in the stitching plane) of the tuft to be closely compressed throughout to a small diameter while at each side of the middle each of said sections eX- pands or spreads sufficiently to n iake a soft,

. loose mass. .Said cord or yarn sections are held to each other and closely compressed midway between their ends by 'thread extending through and around the bundle of i cords in a plane transverseto the length of the tuft (the stitching plane), wherebyv substantiall)7 all ofsaid sect-ions are penetrated by threads and the entire group of sections drawn closely together, so that the portion .of said group or bunch in the stitching plane .is closely compressed vthroughout.

The sewing may be one in anyT desired manner. The drawing illustrate the sewing as having-been donevv by what is'known as vchain stitches, only one thread being used,

and that being carried by a needle which penetrates'the fabric, a hook below the fabric eing used to form the thread into a loop through which' another loop of the thread is drawn during the making of the next stitch, and so on.

l claim as my invention:

1. A tuft comprisi'nglaA bunch ofvshortsections of cord or yarn and thread extending transversely through vsaid bunch in straight stitches, the stitches crossing each other at 2. A tuft comprising a bunch' of lshort sec i tions of cord or yarnV and thread extending tion of the surface of the tu'ft andis'fol'ded I backward upon itself to forni aloop .and again extends through the loop, 1112. The tfwoportionsof this new loop are designated, respectively, 1'7, and 18. Then the thread again extends through the tuft along the-portion, 16'.'

This portion of the Then the thread again extends through the tuft, referably at one side of the axis, E, and t nough'the loop, 17-18, this rportion of the'kthrezull being marked 21'. lhen t-he thread again turns forward over a portion of the surface of the tuft and then backward to form a. loop, the two portions of the loop being marked, re.- spectively, 22 and 23.'

Then' the thread ends' at any desired transversely through said, vbunch in straight stitches, each stitchpassing at one side of the axis of'the bunch. l

3. A tuft comprising a bunch of shortsections of cord or yarn and tightly-drawn thread extending'in straight stitches transvversely through'said bunch of cords between the -ends of'and at one side of the. axis of said bunch and extending over the-surfaceof said bunch.

4. A tuft comprising a bunch of short sections of cord or yarn and thread extending transversely through said bunch in straight stitches, the stitches crossing each other at diverse points in the stitching plane, the portion of the bunch in the stitching plane being closely compressed throughout.-
